Boiling

And you want to have at least two ways to purify your water.

Boiling is the simplest solution.

You just have a pot.

If you have a wood stove or if you have even a gas grill outside, get your water to a rolling boil for at least a minute, up to three minutes if you're at higher altitude.

Making it takes about two minutes, You can heat some water up about 175 degrees.

You don't need it to be boiling.

Boiling actually scorches the leaf a bit and it can destroy some of that valuable EGCG.

And you just whisk full teaspoon of it into the water that's maybe 1.5 to 2 grams and then whisk it in until it's smooth.

If you squeeze in some lemon, it can actually multiply how much EGCG you get out of it and how much EGCG survives your digestion.

Pinning those settings down in the lab wouldn't have helped.

Part two is boiling water and a magnet.

Two things with nothing in common at the level of atoms.

And they come out with the same number.

In the early to mid-60s, working on particle physics, he wrote that he had to clutch at straws.

What got him out was an idea about taking a problem one slice of scale at a time.

And in 1966, he realized it should work for boiling water and magnets.

And then it just worked?

To say that there is, is altogether wanton.

the view that the heat of the sun's rays intercepted in the clouds is the cause of these phenomena is equally unattractive this too is a most careless explanation thunder lightning and the rest must have a separate and determinate cause assigned to them on which they ensue but this theory does nothing of the sort it is like supposing that water snow and hail existed all along and were produced when the time came and not generated at all as if the atmosphere brought each to hand out of its stock from time to time they are concretions in the same way as thunder and lightning are discretions so that if it is true of either that they are not generated but pre-exist the same must be true of the other again how can any distinction be made about the intercepting between this case and that of interception in denser substances such as water water too is heated by the sun and by fire yet when it contracts again and grows cold and freezes no such ejection as they describe occurs though it ought on their theory to take place on a proportionate scale Boiling is due to the exhalation generated by fire, but it is impossible for it to exist in the water beforehand.

And besides, they call the noise hissing, not boiling.

But hissing is really boiling on a small scale, for when that which is brought into contact with moisture and is in process of being extinguished gets the better of it, then it boils and makes the noise in question.

Similarly, when a liquid boils to become a gas, energy is used to completely overcome the intermolecular forces, allowing particles to move freely and rapidly.

Boiling happens at a specific temperature, the boiling point, and it occurs throughout the liquid.

Don't confuse this with evaporation which happens only at the surface and can occur at any temperature below the boiling point.

Here's a critical concept that examiners love to test.

What is the difference between evaporation and boiling? Answer.

Evaporation occurs at the surface at any temperature.

Boiling occurs throughout the liquid at a specific temperature.

How did you do? If you got all five, brilliant.
